Transfer Learning Promotes 6G Wireless Communications Recent Advances and Future Challenges
ABSTARCT :
In the coming 6G communications, network densification, high throughput, positioning accuracy, energy efficiency, and many other key performance indicator requirements are becoming increasingly strict. In the future, how to improve work efficiency while saving costs is one of the foremost research directions in wireless communications. Being able to learn from experience is an important way to approach this vision. Transfer learning (TL) encourages new tasks/domains to learn from experienced tasks/domains for helping new tasks become faster and more efficient. TL can help save energy and improve efficiency with the correlation and similarity information between different tasks in many fields of wireless communications. Therefore, applying TL to future 6G communications is a very valuable topic. TL has achieved some good results in wireless communications. In order to improve the development of TL applied in 6G communications, this article performs a comprehensive review of the TL algorithms used in different wireless communication fields, such as base stations/access points switching, indoor wireless localization and intrusion detection in wireless networks, etc. Moreover, the future research directions of mutual relationship between TL and 6G communications are discussed in detail. Challenges and future issues about integrate TL into 6G are proposed at the end. This article is intended to help readers understand the past, present, and future between TL and wireless communications.
EXISTING SYSTEM :
? The article also introduces new use cases of 6G in education, media and entertainment, tourism and transport, and logistics, which have not been given adequate treatment in the existing literature.
? This makes the paper to be robust, compensating for the individual lapses in the existing literature.
? The vision of 6G wireless networks, considering the essential requirements and comparing them with the existing generations of wireless communication networks.
? This paper extensively considers existing research, clearly outlining the enabling technologies and the associated challenges, applications, and new applications such as the IoBNT and Digital Replica, which are not given adequate treatment in many related papers.
DISADVANTAGE :
? The distributed nature eliminates the single point of failure problem and enhances security.
? Several technical problems need to be solved to deploy 6G communication systems successfully.
? The backhaul connectivity must be characterized by high-capacity backhaul networks to support a considerable volume of 6G data traffic. High-speed optical fiber and free-space optical (FSO) systems are possible solutions for this problem.
? This paper tried to provide a complete overview of the future 6G communication system considering current trends and efforts by researchers around the world. Some other articles also addressed related issues discretely.
PROPOSED SYSTEM :
• Artificial Neural Networks, Deep Neural Networks have been proposed to enable intelligent networks.
• 6G wireless networks are also proposed to ameliorate social needs, thereby facilitating the actualization of the Sustainable Development Goals (SDGs).
• These challenges have been delineated in this article. Other enabling technologies such as Quantum Communication, Ambient Backscatter Communication Systems (ABCS), Blockchain, UAVs, and more have also been proposed and treated extensively in this paper.
• Quantum communication has been proposed to enable security and facilitate faster processing power for future wireless networks.
ADVANTAGE :
? The 5G paradigm will be further developed and expanded in 6G. However, the 6G system will increase performance and maximize user QoS several folds more than 5G, along with some exciting features.
? It is anticipated that 6G will require a new key performance indicator (KPI) drivers besides the KPIs of 5G communication systems.
? BCI services necessitate higher performance metrics compared to what 5G delivers.
? Researchers have been working on enhancing the performance and overcoming the challenges of these technologies.
? White light based on different wavelengths will beneficial to accelerate the throughput performance via wavelength division multiplexing, leading to potentially 100+ Gbps for ultra-high-data-rate VLC access points.
